Miniaturized Wideband Ultraviolet Imaging Spectrograph for Deep Space Exploration

Deep space exploration is the main means for mankind to study the origin, evolution and current situation of the solar system and the universe, to further understand the formation and evolution of the earth's environment, and to understand the relationship between space phenomena and the earth's natural system. Deep space exploration, which mainly includes lunar exploration, planetary exploration, interplanetary exploration and interplanetary exploration, has become a new growth point and research hotspot, and is also the international research direction. Ultraviolet optical remote sensing (50-380 nm) load mainly detect targets include planets (include satellite of the planet, such as the moon, etc.),atmosphere and magnetosphere object surface, can obtain the traditional field and the particles in place observation is difficult to capture the full picture of the material and energy transport. UV remote sensing is an new important technology to study the solar system and its evolution, and it also can be used for searching extraterrestrial life information . Explorations on the probe of the project will focus on miniaturization, large dynamic, intelligent processing on-board and other special requirements. This project will study the miniaturization of wide spectrum of ultraviolet detection technology, submit a miniaturized wide spectrum imaging spectrometer prototype, spectrum covered 50-200 nm, 2-3 nm spectral resolution, weighing less than 4 kg. This project will fill the blank of the detection of deep space small ultraviolet imaging spectrometry in China, provides technical reserves for subsequent including planet detection, solar system marginal deep space exploration program.
